JOHN E. GOLDEN, OF DUNIVIORE, PENNSYLVANIA.

HORSESHOE.

Application filed March 25, 1913.

To all whom it may concern:

Be it known that 1, JOHN E. GOLDEN, a citizen of the United States, residing at Dun more, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to h0rse-shoes, and is directed more particularly to the class of shoes in which provision is made for insertion and removal of calks which are adapted for use under extraordinary working conditions.

As a rule, calks sharpened to meet the requirements of icy streets for instance, make a poor substitute for the flat base calks generally used under ordinary working conditions. Sharp calks will be embedded in the ice, but when used on impenetrable surfaces make an unsteady footing.

The present invention contemplates among other objects the provision of a shoe which will insure a solid and steady footing when used under ordinary working conditions, and at the same time present a good gripping surface to the road; a shoe in which sharpened calks may be inserted readily when occasion demands, without the removal. of the shoe, and removed similarly. Means are provided for retaining the inserted calks locked in position so as to preclude any possibility of their being jarred loose t5 and dropping out under working conditions,

and these and other objects are accomplished by a device which is simple and practical and economical of manufacture.

An embodiment of my invention selected with a view to readily illustrate its principles, is shown in the accompanying drawing, made a part hereof, and in which Figure 1 is a bottom plan view; Fig. 2 a side elevation; Fig. 3 a sectional view on the lines 3--3 of Fig. 2; Fig. 4 a similar view on the lines 4i4 of Fig. 3; and Fig. 5-

a detail view in perspective of a means for locking a calk in position in the shoe.

Referring specifically to the drawing, in which like numerals designate like parts in the specification, the numeral 6 designates the body portion of a horse shoe on the toe and heel sections of which are raised shoulders 7. Under ordinary working conditions these shoulders are intended to perform the function of the well known flat surface Specification of Letters Eatent.

shoe just described available and advan- 1 tageous for use under extraordinary working conditions: such for instance, as where an antislipping calk is desirable, but which can be inserted or removed without the removal of the shoe from the hoof. The embodiment of such means herein illustrated, consists in providing each raised shoulder with a mortise 10, shown in side elevation, plan, and section, in Figs. 2, 8, and 4, respectively. Into this mortise there is driven, from the road engaging surface of the shoulder, a threaded bore 11, which has an opening 12 in one side. The purpose of this opening is to allow a threaded stud 13, carried by a tenon 14:, to pass into the center of the bore 11 when the tenon is inserted into the mortise. As best seen in Fig. 3, the mortise is of smaller dimensional area at one end than it is at the other end, and the tenon is beveled correspondingly to make a neat fit when inserted. The stud on the tenon is preferably bent slightly out of a perpendicular with the tenon for purposes now to be shown. A calk 15, having a threaded shank 16, is made to thread into the bore 11 in the raised shoulders. The shank is in turn provided with a threaded bore 17 for engagement with the threaded stud 13 of the tenon.

When it is desired to use the sharpened calk for extraordinary working conditions, the tenon 14- is inserted into the mortise 10, the threaded stud 13, passing through the opening 12 into the center of the threaded bore 11 in the raised shoulder. The calk is now threaded into this bore, the threaded stud on the tenon at the same time fitting into the internal bore 17 of the calk, and causing a locking between the calk and the tenon. In addition to the locking action just described, there is another, caused by the stud 13 on the tenon being out of perpendicular arrangement with relation to the surface of the tenon. As seen in Fig. 3, both tenon and mortise are slightly beveled, and

as shown in Fig. 4, the stud 13 is in slightly angular relation with theinner sides of the threaded bore 11. Consequently, when the calk is threaded into this bore, there will be a pulling action on the stud which tends to lock both stud and calk.

From the foregoing it will be seen that l have devised a simple and practical means of producing the results previously enumerated.

WhileI have herein shown the invention in the manner illustrated, it is understood that I do not wish'to limit myself to the particular structure shown, as many modifications of the general idea are contemplated. What I do claim, and desire to secure by Letters'Patent is 1. A horse-shoe comprising a body portion having a toe section and heel sections; raised shoulders on said sections; each shoulder being mortised, and provided with a bore extending from the road engaging surface of the shoulder into the mortise; a

tion having a toe section and heel tenon provided with a stud fitting in said mortise; and a calk secured in each shoulder and threaded to the stud on each tenon.

2. A horse-shoe comprising a body porsections; raised shoulders on said sections; each shoulder being mortised' and provided with a threaded bore extending, from the road engaging surface of the shoe into the mortise;

. said bore having an opening in one side which forms a slot extending from the road engaging surface of the shoulder into the mortise; a tenon having a threaded stud fitting in said mortise; and a calk threaded into each shoulder and to the tenon therein.

3. A horse-shoe comprising a body portion having a toe section and heel sections; raised shoulders on said sections; each shoulder being mortised and provided with a bore extending from the road engaging surface of the shoulder into the mortise; said bore being open at one side to form a slotted opening extending from the road engaging surface of the shoulder into the mortise.

4. A horse-shoe comprising a body portion having a toe section and heel sections; raised shoulders on said sections; each shoulder being mortised and provided with a threaded bore extending from the road engaging surface of the shoulder into the mortise; said threaded bore being open at one portion to form a slot extending from the road engaging surface of the shoulder into the mortise; a tenon having a threaded stud fitting in said mortise; and a calk having a threaded shank secured in said shoulder and locked to said stud on said tenon.

5. A horse-shoe comprising a body portion having a toe section and heel sections; raised shoulders on said sections; each shoulder being mortised and provided with a threaded bore open at one portion to form a slot extending from the road engaging surface of the shoulder into the mortise; a tenon having a threaded stud fitting in said mortise, the stud on the tenon being in angular relation with the inner walls of the threaded bore when inserted; and a calk having a threaded shank and provided with an internal threaded bore locked in each shoulder, the threaded shank of said calk being embraced by said threaded bore in each shoulder, and the threaded bore in said shank embracing the threaded shank on each tenon.

In testimony whereof I afiix my signature in the presence of two subscribing witnesses.
